So, you don't have any factual data to back your claim. Just as I suspected.
You're funny.
"Factual data" as you call it does not exist. What do you want from me? A video? A Process Specification signed by one of my Professional Engineer cohorts? Yeah right. You still wont believe it.
YOU build the "factual data" yourself by physically trying a procedure that a cave man could follow.
You claimed "Fact is, the EZlube zerks are not used by any OEM and has no relation to leaky seals." - Easily disproved, by many of those here who have them installed from the factory (and have found that the factory also pumped grease past the seal and into the brakes).
You claimed "Good, working seals can retain significant pressure." I quoted the spec from a well known manufacturer for common axle seals - 10 psi. You claimed "It takes more effort and pressure to push grease thru a zerk fitting than it does thru the EZlube system!!!!" That's emphasizing a complete non-sequitur because the only thing that matters to the discussion is how much it takes to push grease through and out the outer bearing vs. the seal. But you can't provide any reference to how much pressure it takes to do that, even though you claim it to be less than through the zerk.
You claimed "The rubber cap for example, will relieve pressure in the closed system long before the seal ever will," showing you really don't even understand how the system works - it is not, and isn't designed to be, a pressurized system, except during the brief time while replenishing the grease, at which time the cap is off.
And, for the topper, you claimed "It is 100% impossible to blow out a good working seal via EZlube zerk," when there are lots of examples of exactly that happening if one does only a minimal amount of searching, and even the manufacturer warns to only pump grease slowly while the hub is moving, because of exactly that problem.
